To all whom it may concern:

Be it known that` I, MICHAEL B. GREEN, a citizen of the. United States,residing 'at -Memphis, in the county of Shelby and State of Tennessee,have inyentednew'and useful Improvements in Compression-Boxes, ofwhich-)the following is a specification.

This invention relates 'tov` compression boxes and 'more' particularlytof that type 'which are specifically adapted -ffor use in connectionwith cotton seeddproeesses.-

The principal 4obect Aof the 'invention is to.4

obviate the diiicu ties encountered in the usevof the presentperforatedplate and to obtain, a quantityA `of oil Afrom' the' cairevinexcess of that obtained through-thev use of -said plate.V While theantiquated hairmat was the -ideal .base for compression boxes,

vthe.proezas was extremely slow and vcan not:

be used at the' present day owing to the slowness of operationandrto thealmost prohibitive expense'in producing these mats.

It is the object of this invention,fthere i forefto secure theeffectiveness or the pro ducing qualities of the hair mat with the speedof the .perforated plate land to obviate4 i the difficulties encounteredwith the latter,

such as lack of porosity and inability to stand the Strain.

Further objects of this invention will ap- .pear as the following specicdescription is` read inconnection with the accompanying d hichfo artfthisalic-l rawmgw rmsap o' P-p a wranged. in recesses in the sidebars.'v

Extendingup -from the base of the niachine are four separate columns orrods 1'9 connected together at their upper ends byfa'n abutment' plate'201v and slidably mounted' upon these rods are aplurality of boxes,all

of which carry'mats-similarto the one'just described. These iboxes areprovided with the flanges 4 and 5 and each is-provided with -an opening21 through'which the oil drains theV boxes preferably conformed "toYtheoutline of the upper surface of the mat, as shown, and when the mealcake is removed,
